Hello, since a couple days after updating to v1.4.4 i have the following issue:

This happens whenever i try to launch jobber. Consequentially, none of my cron jobs are currently running.

This is jobber v1.4.4 on ubuntu 18.04, installed via the .deb. I already tried to purge and reinstall jobber, no dice. If you need any other information, just ask.

After running sudo /usr/lib/x86_64-linux-gnu/jobbermaster, the issue is apparently

So yes, it was just a bad config. A more accessable log would go a long way in these situations, maybe the daemon can log to /var/log/?

Yeah...

I also have this issue. Found this solution: to delete all files in /var/log/jobber and restart the jobbermaster service.

Yeah...
🤣

@dshearer My go skills are too absent to be sure, but I suspect assigning a new value to the variable and then trying to use the old value does not work:

self.jfile, err = jfile.Activate(self.user)
if err != nil {
    self.jobRunner.Start(self.jfile.Jobs, self.Shell)
